Product name: T38 Thread 1830mm Length Diamond MM Extension Rod For Construction Machinery
Product category: Drilling rod
Threaded Connection: T38
Length: 1830mm
KINGDRILLING Alloy steel with a high strength is used to make threaded drill pipes. High-precision CNC machines are used to machine all tracks and threads. Rapid heating and cooling are used to induce the threads after induction hardening. The mechanical qualities of the drill pipe are enhanced and its service life is guaranteed by precision temperature control heat treatment equipment.
Total carburization hardens the outer steel body and raises the carbon content of the drill pipe's outer layer. Drilling activities in complicated rocks and terrains can be completed with great precision and efficiency by using solid thread drill bits that fit exactly against the inner wall of the drill bit.

FAQ:
1. How should one use a drilling pipe?
The device used to transfer power during drilling operations is the drill rod. Many parts, including the drill, stabilizers, drilling pipe, drill collars, special connectors, and Kelly, usually make up a drill string. Controlling the drill bit, applying weight on bit (WOB), transmitting power, carrying out specific operations like cement extrusion and managing subterranean mishaps, and (4) delivering drilling fluid are the five primary responsibilities of the drill string.
2. What are the benefits of using heavy-duty drill pipe?
a. When drilling a deep well, heavy drill pipe can be used to replace a portion of the drill collar. This will increase drilling capacity, improve load, and decrease torque.
b. Using a simple method that can reduce tripping time, to pick up the sub and safety clamp that are not in use during drilling operations.
c. Drilling directional wells at a high speed with low torque minimizes string abrasion and fracture without differential pressure and sticking due to drill collar's lower steel grade and tiny touching area with the well wall.
3. What is a drill rod?
A drill rod is a form of bar stock machined to produce tools such as drill bits, taps, dowel pins, shafts, reamers, files, punches and hammers. It's soft enough to shape but can be heated up to revert back to the hardness. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter.
